Help ID a Plane

I've got no picture, and I'm sorry about that, but here's the scoop...

While in ATL and taxiing out to Runway 26L (I was on Delta flight 1020) on Sunday, I saw what I thought was a 717 taking off from 26L. I figured, okay, AirTran, but it seemed like it was a special scheme I had never seen before. The only thing I caught was the tail, which had a design that had a T encircled. I couldn't tell you what colors because it was at night and I only saw the plane for like one second but it seemed like there was some red in the scheme.

I quickly checked a.net to see if it was any of the football schemes and it wasn't - though I did see the Atlanta Falcons jet at a gate as well as the Pink Delta AND the Skyteam 767-400 (but I saw those jets on the 11th, when I had a layover there to go to Pensacola).

Maybe it wasn't a 717... maybe it was a regional jet... or maybe I saw a brand new AirTran logojet? What do you guys think?
